The Kansas City Chiefs say rookie defensive tackle Glenn Dorsey should miss about a week after spraining his left knee in practice during the weekend. Elsewhere, Seahawks OL Chris Gray retired because of a lower back and spine injury that threatened his ability to walk.

The agent for LeCharles Bentley says the center has asked for and received his release from the Cleveland Browns. Bentley's agent Jonathan Feinsod says that his client wants to resume his career somewhere else. The Plain Dealer first reported Bentley's release on its website.

The New York Jets signed first-round pick Darrelle Revis on Wednesday, ending the touted cornerback's lengthy holdout. Revis, selected 14th overall after New York traded up to draft him, missed 22 practices including Wednesday's single practice and the team's preseason opener last Friday against Atlanta since training camp started July 27.
